Abstract
Natural killer (NK) cells were originally described as cytolytic effector cells, but since then have been recognized to possess regulatory functions on immune responses. Chemokines locate NK cells throughout the body in homeostatic and pathological conditions. They may also directly stimulate immune cells. CCL18 is a constitutive and inducible chemokine involved in allergic diseases. The aim of this study was to evaluate CCL18’s effect on NK cells from allergic and nonallergic donors in terms of both chemotactic and immune effects. Results showed that CCL18 was able to induce migration of NK cells from nonallergic donors in a G-protein-dependent manner, suggesting the involvement of a classical chemokine receptor from the family of seven-transmembrane domain G-protein-coupled receptors. In contrast, NK cells from allergic patients were unresponsive. Similarly, CCL18 was able to induce NK cell cytotoxicity only in nonallergic subjects. Purified NK cells did not express CCR8, one of the receptors described to be involved in CCL18 functions. Finally, the defect in CCL18 response by NK cells from allergic patients was unrelated to a defect in CCL18 binding to NK cells. Overall, our results suggest that some NK cell functions may be defective in allergic diseases.

Abstract
BACKGROUND Asthma severity has been linked to exposure to gram-negative bacteria from the environment that are recognized by NOD1 receptor and are present in house dust mite (HDM) extracts. NOD1 polymorphism has been associated with asthma. OBJECTIVE We sought to evaluate whether either host or HDM-derived microbiota may contribute to NOD1-dependent disease severity. METHODS A model of HDM-induced experimental asthma was used and the effect of NOD1 deficiency was evaluated. Contribution of host microbiota was evaluated by fecal transplantation. Contribution of HDM-derived microbiota was assessed by 16S ribosomal RNA sequencing, mass spectrometry analysis, and peptidoglycan depletion of the extracts. RESULTS In this model, loss of the bacterial sensor NOD1 and its adaptor RIPK2 improved asthma features. Such inhibitory effect was not related to dysbiosis caused by NOD1 deficiency, as shown by fecal transplantation of Nod1-deficient microbiota to wild-type germ-free mice. The 16S ribosomal RNA gene sequencing and mass spectrometry analysis of HDM allergen, revealed the presence of some muropeptides from gram-negative bacteria that belong to the Bartonellaceae family. While such HDM-associated muropeptides were found to activate NOD1 signaling in epithelial cells, peptidoglycan-depleted HDM had a decreased ability to instigate asthma in vivo. CONCLUSIONS These data show that NOD1-dependent sensing of HDM-associated gram-negative bacteria aggravates the severity of experimental asthma, suggesting that inhibiting the NOD1 signaling pathway may be a therapeutic approach to treating asthma.

Abstract
The transcription factor BCL11B/CTIP2 is a major regulatory protein implicated in various aspects of development, function and survival of T cells. Mitogen-activated protein kinase (MAPK)-mediated phosphorylation and SUMOylation modulate BCL11B transcriptional activity, switching it from a repressor in naive murine thymocytes to a transcriptional activator in activated thymocytes. Here, we show that BCL11B interacts via its conserved N-terminal MSRRKQ motif with endogenous MTA1 and MTA3 proteins to recruit various NuRD complexes. Furthermore, we demonstrate that protein kinase C (PKC)-mediated phosphorylation of BCL11B Ser2 does not significantly impact BCL11B SUMOylation but negatively regulates NuRD recruitment by dampening the interaction with MTA1 or MTA3 (MTA1/3) and RbAp46 proteins. We detected increased phosphorylation of BCL11B Ser2 upon in vivo activation of transformed and primary human CD4(+) T cells. We show that following activation of CD4(+) T cells, BCL11B still binds to IL-2 and Id2 promoters but activates their transcription by recruiting P300 instead of MTA1. Prolonged stimulation results in the direct transcriptional repression of BCL11B by KLF4. Our results unveil Ser2 phosphorylation as a new BCL11B posttranslational modification linking PKC signaling pathway to T-cell receptor (TCR) activation and define a simple model for the functional switch of BCL11B from a transcriptional repressor to an activator during TCR activation of human CD4(+) T cells.

Abstract
Apicomplexan parasites have unique apical rhoptry and microneme secretory organelles that are crucial for host infection, although their role in protection against Toxoplasma gondii infection is not thoroughly understood. Here, we report a novel function of the endolysosomal T. gondii sortilin-like receptor (TgSORTLR), which mediates trafficking to functional apical organelles and their subsequent secretion of virulence factors that are critical to the induction of sterile immunity against parasite reinfection. We further demonstrate that the T. gondii armadillo repeats-only protein (TgARO) mutant, which is deficient only in apical secretion of rhoptries, is also critical in mounting protective immunity. The lack of TgSORTLR and TgARO proteins completely inhibited T-helper 1-dependent adaptive immunity and compromised the function of natural killer T-cell-mediated innate immunity. Our findings reveal an essential role for apical secretion in promoting sterile protection against T. gondii and provide strong evidence for rhoptry-regulated discharge of antigens as a key effector for inducing protective immunity.

Abstract
Pollution, including polycyclic aromatic hydrocarbons (PAH), may contribute to increased prevalence of asthma. PAH can bind to the Aryl hydrocarbon Receptor (AhR), a transcription factor involved in Th17/Th22 type polarization. These cells produce IL17A and IL-22, which allow neutrophil recruitment, airway smooth muscle proliferation and tissue repair and remodeling. Increased IL-17 and IL-22 productions have been associated with asthma. We hypothesized that PAH might affect, through their effects on AhR, IL-17 and IL-22 production in allergic asthmatics. Activated peripheral blood mononuclear cells (PBMCs) from 16 nonallergic nonasthmatic (NA) and 16 intermittent allergic asthmatic (AA) subjects were incubated with PAH, and IL-17 and IL-22 productions were assessed. At baseline, activated PBMCs from AA exhibited an increased IL-17/IL-22 profile compared with NA subjects. Diesel exhaust particle (DEP)-PAH and Benzo[a]Pyrene (B[a]P) stimulation further increased IL-22 but decreased IL-17A production in both groups. The PAH-induced IL-22 levels in asthmatic patients were significantly higher than in healthy subjects. Among PBMCs, PAH-induced IL-22 expression originated principally from single IL-22- but not from IL-17- expressing CD4 T cells. The Th17 transcription factors RORA and RORC were down regulated, whereas AhR target gene CYP1A1 was upregulated. IL-22 induction by DEP-PAH was mainly dependent upon AhR whereas IL-22 induction by B[a]P was dependent upon activation of PI3K and JNK. Altogether, these data suggest that DEP-PAH and B[a]P may contribute to increased IL22 production in both healthy and asthmatic subjects through mechanisms involving both AhR -dependent and -independent pathways.

Abstract
Phleum pratense pollen was exposed to NO(2) in a reactor allowing a continuous analysis of NO(2) concentration by FTIR. The uptake coefficient of NO(2) on pollen was calculated postulating a first order kinetic reaction and a value of (1.1 ± 0.1) x 10(-7) was determined. NO(2) uptake was faster when the pollen water content was increased and when the pollen was pre-treated with ozone. The effect of NO(2) exposure on pollen allergic properties was investigated by quantifying Th2- and Th1-associated chemokines in a model of human dendritic cells. Cellular analysis clearly showed that cells exposed to fumigated pollen favored the production of chemokines known to promote Th2-cell responses. Altogether these data demonstrate that NO(2) uptake by pollen directly correlates with increased Th2 response in human cells,and are in favor of the involvement of NO(2) pollution in the increase of allergic diseases.

Abstract
RATIONALE Pattern recognition receptors are attractive targets for vaccine adjuvants, and polymorphisms of the innate receptor NOD1 have been associated with allergic asthma. OBJECTIVES To elucidate whether NOD1 agonist may favor allergic asthma in humans through activation of dendritic cells, and to evaluate the mechanisms involved using an in vivo model. METHODS NOD1-primed dendritic cells from allergic and nonallergic donors were characterized in vitro on their phenotype, cytokine secretion, and Th2 polarizing ability. The in vivo relevance was examined in experimental allergic asthma, and the mechanisms were assessed using transfer of NOD1-conditioned dendritic cells from wild-type or CCL17-deficient mice. MEASUREMENTS AND MAIN RESULTS NOD1 priming of human dendritic cells promoted a Th2 polarization profile that involved the production of CCL17 and CCL22 in nonallergic subjects but only CCL17 in allergic patients, without requiring allergen costimulation. Moreover, NOD1-primed dendritic cells from allergic donors exhibited enhanced maturation that led to abnormal CCL22 and IL-10 secretion compared with nonallergic donors. In mice, systemic NOD1 ligation exacerbated allergen-induced experimental asthma by amplifying CCL17-mediated Th2 responses in the lung. NOD1-mediated sensitization of purified murine dendritic cells enhanced production of CCL17 and CCL22, but not of thymic stromal lymphopoietin and IL-33, in vitro. Consistently, adoptive transfer of NOD1-conditioned dendritic cells exacerbated the Th2 pulmonary response in a CCL17-dependent manner in vivo. CONCLUSIONS Data from this study unveil a deleterious role of NOD1 in allergic asthma through direct induction of CCL17 by dendritic cells, arguing for a need to address vaccine formulation safety issues related to allergy.

Abstract
Eosinophils are potent inflammatory cells with numerous immune functions, including antigen presentation and exacerbation of inflammatory responses through their capacity to release a range of largely preformed cytokines and lipid mediators. Thus, timely regulation of eosinophil activation and apoptosis is crucial to develop beneficial immune response and to avoid tissue damage and induce resolution of inflammation. Natural Killer (NK) cells have been reported to influence innate and adaptive immune responses by multiple mechanisms including cytotoxicity against other immune cells. In this study, we analyzed the effect of the interaction between NK cells and eosinophils. Co-culture experiments revealed that human NK cells could trigger autologous eosinophil activation, as shown by up-regulation of CD69 and down-regulation of CD62L, as well as degranulation, evidenced by increased CD63 surface expression, secretion of eosinophil cationic protein (ECP) and eosinophil derived neurotoxin (EDN). Moreover, NK cells significantly and dose dependently increased eosinophil apoptosis as shown by annexin V and propidium iodide (PI) staining. Direct contact was necessary for eosinophil degranulation and apoptosis. Increased expression of phosphorylated extracellular signal-regulated kinase (ERK) in cocultured eosinophils and inhibition of eosinophil CD63 expression by pharmacologic inhibitors suggest that MAPK and PI3K pathways are involved in NK cell-induced eosinophil degranulation. Finally, we showed that NK cells increased reactive oxygen species (ROS) expression by eosinophils in co-culture and that mitochondrial inhibitors (rotenone and antimycin) partially diminished NK cell-induced eosinophil apoptosis, suggesting the implication of mitochondrial ROS in NK cell-induced eosinophil apoptosis. Pan-caspase inhibitor (ZVAD-FMK) only slightly decreased eosinophil apoptosis in coculture. Altogether, our results suggest that NK cells regulate eosinophil functions by inducing their activation and their apoptosis.

Abstract
CCL18 is both a constitutively expressed and an inducible chemokine, whose role in the inflammatory reaction is poorly known. The aim of this study was to evaluate whether CCL18 has the capacity to attract human T cells with a regulatory function (regulatory T cells [Treg]). Results from chemotaxis assays performed on different types of Treg showed that CD4(+)CD25(+)CD127(low) cells, but neither T regulatory type 1 clones nor Treg differentiated in vitro with anti-CD3/CD46 mAbs, were recruited by CCL18 in a dose-dependent manner. CCL18-recruited memory CD4(+) T cells were enriched in CD25(high), CD25(+)CD127(low), latency-associated peptide/TGF-β1, and CCR4-expressing T cells, whereas there was no enrichment in Foxp3(+) cells as compared with controls. Stimulated CCL18-recruited memory T cells produced significantly increased amounts of the regulatory cytokines IL-10 and TGF-β1, as well as IL-4, but not IFN-γ and IL-17. Cell surface CCL18 binding was found predominantly on IL-10(+) (26.3 ± 5.8%) and on a few latency-associated peptide/TGF-β1(+) (18.1 ± 1.9%) and IL-4(+) (14.5 ± 2.9%) memory T cells. In an in vivo model of SCID mice grafted with human skin and reconstituted with autologous PBMCs, the intradermal injection of CCL18 led to the cutaneous recruitment of CD4(+), CD25(+), and IL-10(+) cells, but not Foxp3(+) cells. Furthermore, CCL18-recruited memory T cells inhibited the proliferation of CD4(+)CD25(-) effector T cells through an IL-10-dependent mechanism. These data suggest that CCL18 may contribute to maintaining tolerance and/or suppressing deleterious inflammation by attracting memory Tregs into tissues, particularly in the lung, where it is highly and constitutively expressed.

Abstract
BACKGROUND The prevalence of allergic diseases has increased in the last 20 years, and a number of studies have shown that diesel exhaust particle-associated polyaromatic hydrocarbons can exacerbate the allergic reaction. Much less is known about their potential capacity to generate a T(H)2-type allergic reaction in nonatopic subjects. OBJECTIVE The aim of this study was to test the hypothesis that diesel exhaust exposure might favor, in nonatopic donors, T(H)2-type cell recruitment, either through increased production of T(H)2-attracting chemokines or decreased production of T(H)1-attracting chemokines. METHODS PBMCs from nonatopic donors were incubated with diesel exhaust particle-polyaromatic hydrocarbons, and the supernatants were evaluated for the presence of pro-T(H)1 chemokines (IFN-gamma-induced protein 10 and monokine Induced by IFN-gamma) and pro-T(H)2 chemokines (macrophage-derived chemokine, I-309, and pulmonary and activation-regulated chemokine) by means of ELISA. The functional effect was evaluated by using chemotaxis assays with polarized T(H)1 and T(H)2 cells. RESULTS Diesel exhaust exposure of PBMCs from nonatopic donors induced a late increase after 48 hours in pulmonary and activation-regulated chemokine mediated by IL-13 and a decrease in IFN-gamma-induced protein 10 levels selectively at both the protein and mRNA levels. The functional effect of these chemokine variations resulted in an enhanced chemotaxis of T(H)2, but not T(H)1, cells. CONCLUSION These findings show that diesel exhaust exposure might be involved in the genesis of allergic diseases by differentially regulating chemokines favoring the recruitment of T(H)2 cells in nonatopic subjects. CLINICAL IMPLICATIONS Environmental factors, especially air pollution, might favor the genesis of allergic diseases.

Abstract
Allergic asthma is associated with a pulmonary recruitment of Th type 2 cells, basophils, and eosinophils, mainly linked to chemokine production. CCL18 is a chemokine preferentially expressed in the lung, secreted by APCs, induced by Th2-type cytokines, and only present in humans. Therefore, CCL18 may be involved in allergic asthma. PBMC from asthmatics allergic to house dust mite cultured in the presence of Dermatophagoides pteronyssinus 1 (Der p 1) allergen secreted CCL18, 48 and 72 h after stimulation, whereas those from healthy donors did not. Part of CCL18 was directly derived from Der p 1-stimulated plasmacytoid dendritic cells, whereas the other part was linked to monocyte activation by IL-4 and IL-13 produced by Der p 1-stimulated T cells. In bronchoalveolar lavages from untreated asthmatic allergic patients, CCL18 was highly increased compared with controls. Functionally, CCL18 preferentially attracted in vitro-polarized Th2 cells and basophils, but not eosinophils and Th1 cells, and induced basophil histamine and intracellular calcium release. These data show a new function for CCL18, i.e., the recruitment of Th2 cells and basophils, and suggest that CCL18 may play a predominant role in allergic asthma.

Abstract
CCR5 is one of the major inflammatory chemokine receptors with potential therapeutical applications in humans. However, the redundancy of chemokines and their receptors, and the species specificity of chemokine receptor antagonists pose challenges to understanding of the role they play in pharmacological situations. To address this question, we used a humanized severe combined immunodeficient mouse model grafted with human skin and autologous leukocytes, and evaluated the effect of a blocking antibody against human CCR5, on CCL5-induced cutaneous leukocyte recruitment in vivo. At baseline, CCL5 induced a significant recruitment of T cells mainly of the memory phenotype, of monocytes/macrophages, eosinophils, and IFN-gamma(+) but not IL-4(+) and IL-5(+) cells. In vivo, anti-CCR5 antibody was able to almost completely inhibit the recruitment of monocytes/macrophages and T-helper (Th)1-type cells to inhibit partially the attraction of memory T cells, but had no effect on eosinophil infiltration, although all these cell types express other CCL5 binding chemokine receptors than CCR5. These results indicate that the in vivo environment regulates target cell specificity of CCL5 leading to differential cell recruitment, suggesting that antagonizing CCR5 receptor may be of therapeutic value in diseases such as acquired immuno deficiency syndrome, where CCL5/CCR5, monocytes, and Th1-type cells play a predominant role.

Abstract
BACKGROUND AND AIMS Recent studies with mu opioid receptor (MOR) deficient mice support a physiological anti-inflammatory effect of MOR at the colon interface. To better understand the potential pharmacological effect of certain opiates in inflammatory bowel diseases (IBD), we (1) evaluated the regulation in vivo and in vitro of human MOR expression by inflammation; and (2) tested the potential anti-inflammatory function of a specific opiate (DALDA) in inflamed and resting human mucosa. PATIENTS AND METHODS Expression of MOR mRNA and protein was evaluated in healthy and inflamed small bowel and colonic tissues, isolated peripheral blood mononuclear cells and purified monocytes, and CD4+ and CD8+ T cells from healthy donors and IBD patients. The effect of cytokines and nuclear factor kappaB (NFkappaB) activation on MOR expression in lymphocyte T and monocytic human cell lines was assessed. Finally, DALDA induced anti-inflammatory effect was investigated in mucosal explants from controls and IBD patients. RESULTS MOR was expressed in ileal and colonic enteric neurones as well as in immunocytes such as myeloid cells and CD4+ and CD8+ T cells. Overexpressed in active IBD mucosa, MOR was significantly enhanced by cytokines and repressed by NFkappaB inhibitor in myeloid and lymphocytic cell lines. Furthermore, ex vivo DALDA treatment dampened tumour necrosis factor alpha mRNA expression in the colon of active IBD patients. CONCLUSIONS Given the increased expression of MOR and the ex vivo beneficial effect of DALDA in active IBD, natural and/or synthetic opioid agonists could help to prevent overt pathological intestinal inflammation.

Abstract
The objective of this study was to evaluate if diesel exhausts could favor helper T cell type (Th) 2-associated allergic reactions either through an increased production of Th2-associated chemokines and of their associated receptors or through a decrease of Th1-attracting chemokines and chemokine receptors. Diesel but not allergen exposure of peripheral blood mononuclear cells from subjects with allergy induced a release of I-309, whereas both diesel and Der p 1 induced an early but transient release of monokine induced by IFN-gamma and a late release of pulmonary and activation-regulated chemokine. Although both Th1- and Th2-attracting chemokines were induced, the resulting effect was an increased chemotactic activity on Th2 but not Th1 cells. Surprisingly, diesel induced a late increase in the expression of the Th1-associated CXC receptor 3 and CC receptor 5. T cell CXC receptor 3 upregulation was not associated with an increased migration to its ligands. These two antagonistic effects have been previously reported as a scavenger mechanism to clear chemokines. Altogether, these results suggest that diesel, even without allergen, may amplify a type 2 immune response but that it can also increase late Th1-associated chemokine receptor expression, perhaps as a scavenger mechanism to clear pro-Th1 chemokines and promote the Th2 pathway.

Abstract
Eosinophil, basophil, and T helper 2 (TH2) cell recruitment into tissues is a characteristic feature of allergic diseases. These cells have in common the expression of the chemokine receptor CCR3, which may represent a specific pathway for their accumulation in vivo. Although animal models of allergic reactions are available, findings cannot always be extrapolated to man. To overcome these limitations, we have developed a humanized mouse model of allergic cutaneous reaction using severe combined immunodeficiency mice engrafted with skin and autologous peripheral blood mononuclear cells from allergic donors. Intradermal injection of the relevant allergen into human skin xenografts from allergic individuals induced a significant recruitment of human CD4(+) T cells, basophils, and TH2-type cytokine mRNA-expressing cells, as well as murine eosinophils. Human skin xenografts, atopic status, and autologous peripheral blood mononuclear cell reconstitution were all mandatory to induce the allergic reaction. Next, we addressed the role of CCR3 in the endogenous mechanisms involved in the inflammatory cell recruitment in this experimental model of allergic cutaneous reaction. In vivo administration of an anti-human CCR3-blocking antibody selectively reduced accumulation of eosinophils but not that of CD4(+) cells, basophils, or cells expressing mRNA for TH2-type cytokines. These findings establish a new in vivo model of humanized allergic reaction and suggest that eosinophil migration is mediated mainly through CCR3. Finally, these results suggest that this model might be useful to test human-specific antiallergic modulators.

Abstract
Recently, certain chemokines and chemokine receptors have been preferentially associated with the selective recruitment in vitro of type 1 T cells, such as IP-10 and its receptor CXCR3, or type 2 T cells such as monocyte-derived chemokine (MDC) and eotaxin and their receptors CCR4 and CCR3. Very few models have provided confirmation of these findings in vivo. Taking advantage of the humanized SCID mouse model grafted with autologous human skin, the ability of the chemokines IP-10, MDC, eotaxin, and RANTES to stimulate cell recruitment was investigated. Intradermal IP-10 injection resulted in an influx of CD4+ T lymphocytes but also surprisingly in the recruitment of dendritic cells. MDC recruited mainly CD8+ T lymphocytes, and had little effect on eosinophils. As predicted, eotaxin was a potent inducer of eosinophil and basophil migration, also recruiting CD4+ T cells. RANTES, a ubiquitous chemokine associated with both type 1 and type 2 profiles, was able to recruit all cell types. CXCR3-positive cells were preferentially recruited by IP-10, whereas CCR3- and CCR4-positive cells were predominantly found after injection of eotaxin and MDC. Thus, in a human environment in vivo, some chemokines have the ability to recruit cells expressing chemokine receptors preferentially expressed on type 1 or type 2 cells. Further investigations revealed that MDC and eotaxin induced the recruitment of type 2, but not type 1, cytokine-producing cells. RANTES, on the other hand, induced the migration of both type 1 and type 2 cytokine-secreting cells, whereas IP-10 did not induce the recruitment of either subtype. These studies provide detailed information on the properties of MDC, eotaxin, IP-10, and RANTES as chemotactic molecules in skin in vivo. The use of the humanized SCID mouse model grafted with human skin is validated as a useful model for the evaluation of chemokine function in the inflammatory reaction, and suggests that therapeutic targeting of certain chemokines might be of interest in diseases associated preferentially with a type 1 or type 2 profile.

Abstract
BACKGROUND T lymphocytes are important components of the bronchial inflammatory cell infiltrate in asthma. Because lymphocytes activated in the respiratory tract recirculate to remote glandular and mucosal sites, we previously studied the histologic features of minor salivary glands (MSGs) in bronchial asthma and found an airway-like inflammation with T-lymphocyte infiltration, the presence of mast cells that were often degranulated, and basement membrane thickening but no eosinophil infiltration. OBJECTIVE We sought to investigate the cellular infiltration and cytokine profile in MSGs from untreated asthmatic subjects, steroid-treated asthmatic subjects, and control subjects and to compare these values with those found in bronchial biopsy specimens. METHODS The cellular infiltration was studied by using immunohistochemistry. Cytokine messenger (m)RNA expression for IL-4, IL-5, and IFN-gamma was determined by using in situ hybridization and cytokine immunoreactivity with immunohistochemistry. RESULTS A significant increase in CD4 and IL-4 mRNA(+) cells was observed in MSGs from asthmatic patients (both untreated and steroid-treated subjects) when compared with control subjects, which correlated with the clinical severity of asthma (FEV(1) and Aas score). In contrast to the bronchi, no IL-5 mRNA expression was observed in MSGs, and no difference was observed for MSG IFN-gamma mRNA between the groups. At the level of MSG protein expression, the 3 cytokines were seen, with a significant increase in IL-4 protein expression in steroid-treated asthmatic subjects compared with untreated asthmatic subjects and control subjects, but there were no differences between the groups in IL-5 and IFN-gamma protein expression. CONCLUSION The cytokine mRNA expression pattern observed in the MSGs of asthmatic subjects was different from that found in the bronchi, suggesting a different local immune regulation.

Abstract
The mechanism by which specific immunotherapy exerts its beneficial effect remains unclear. Chemokines are implicated in inflammatory and allergic diseases, in particular via their ability to induce histamine release from basophils, a potential early target of rush venom immunotherapy (RVIT), In this study, the authors evaluated ex vivo regulated upon activation normal T-cell expressed and secreted (RANTES), interleukin 8 (IL-8) and monocyte chemoattractant protein 1 (MCP-1) production and mRNA expression by mononuclear cells (MNC) from nine patients undergoing a 3.5-h ultra rush treatment, before treatment at Day 0 (D0), at the end of the 3.5-h of the rush at Day 4h (D4h), at Day 15 (D15) and Day 45 (D45) after treatment. Increased RANTES release and mRNA expression were observed in 24-h culture of peripheral blood MNC collected at D4h. This was followed by a decrease in the production of RANTES, IL-8 and MCP-1, 45 days after initiation of RVIT. The same pattern was observed after in vitro venom stimulation of MNC. At the mRNA level, similar profiles were observed except for IL-8 mRNA which inversely increased during RVIT. These results suggest that RVIT is associated with a general decrease in chemokines which may explain, in part, the clinical efficacy of specific immunotherapy.

Abstract
We have developed an animal model to study human delayed-type hypersensitivity reactions. Previous studies in humans have shown after tuberculin injection the presence of a mononuclear cell infiltration, with almost no eosinophils, associated with a preferential Th-1-type cytokine profile. Human skin graft obtained from tuberculin-reactive donors was grafted onto the back of severe combined immunodeficient mice. After healing, mice were reconstituted intraperitoneally with peripheral mononuclear cells. Tuberculin and diluent were injected intradermally, and skin biopsies were performed 72 hours later. Skin grafts were divided into two parts, one for immunohistochemistry and one for in situ hybridization studies. Immunohistochemistry was performed on cryostat sections using the alkaline phosphatase anti-alkaline phosphatase technique. In the tuberculin-injected sites as compared with the diluent-injected sites, there were significant increases in the number of CD45+ pan leukocytes and CD4+, CD8+, CD45RO+ T cells but not in CD68+ monocytes/macrophages and EG2 or MBP+ eosinophils. The activation markers CD25 and HLA-DR were up-regulated in the tuberculin-injected sites. In situ hybridization was performed using 35S-labeled riboprobes for interleukin (IL)-2, interferon (IFN)-gamma, IL-4, and IL-5. After tuberculin injection, a preferential Th-1-type cytokine profile was observed with significant increases in the numbers of IL-2 and IFN-gamma mRNA-expressing cells. These results are similar to those reported after tuberculin-induced delayed-type hypersensitivity in humans, suggesting that this model might be useful to study cutaneous inflammatory reaction.

Abstract
Sarcoidosis is a multisystem granulomatous disease associated with the expansion and activation of CD4+ T-lymphocytes and macrophages. To investigate the immunopathology of active and nonactive pulmonary sarcoidosis, we have examined the expression of cytokine gene transcripts in bronchoalveolar lavage cells from 15 patients with active pulmonary sarcoidosis, eight patients with non-active pulmonary sarcoidosis, and nine normal controls. Using in situ hybridization, the percentage of cells expressing messenger ribonucleic acid (mRNA) for interleukin (IL)-1 beta, IL-2, IL-3, IL-4, IL-5, IL-6, IL-10, IL-12 and interferon-gamma (IFN-gamma) were compared in the groups studied. In individuals with active sarcoidosis, there were significantly greater proportions of cells expressing mRNA for IL-2, IL-10, IL-12 and IFN-gamma than in subjects with nonactive disease and normal controls (p < 0.01). There was no significant difference in the percentage of positive cells expressing IL-10 and IL-12 mRNA in the nonactive group compared to the normal controls (p > 0.05). No significant differences in the percentages of IL-3, IL-4 and IL-5 mRNA positive cells were observed between active and nonactive sarcoidosis patients and normal controls (p > 0.05). These results demonstrate that there is a preferential expression of T-helper type 1 cytokines in pulmonary sarcoidosis, and that cytokines related to macrophage activation are the most prominent. In addition, these data implicate an elevated expression of interleukin-2, -10 and -12 and interferon-gamma in active compared to nonactive sarcoidosis.

Abstract
Platelets can be activated by IgE and are therefore involved in IgE-mediated effector mechanisms against parasites and in allergic disorders. Here we show that, besides the low-affinity IgE receptor (Fc epsilon RII/CD23), platelets express the high-affinity receptor for IgE (Fc epsilon RI). Flow cytometry analysis revealed the existence of surface Fc epsilon RI on platelets with a large heterogeneity among individual donors, and a low proportion of platelets co-expressing Fc epsilon RI and FC epsilon RII/CD23. Northern hybridization and reverse transcription polymerase chain reaction confirmed the presence of mRNA encoding the alpha, beta and gamma chains of Fc epsilon RI in platelets and in their megakaryocytic precursors. Cross-linking of Fc epsilon RI with monoclonal antibody (mAb) to alpha chain using either the whole molecule or F(ab')2 triggered platelet cytotoxicity for Schistosoma mansoni larvae. Anti-Fc epsilon RII/CD23 mAb significantly inhibited IgE- or Fc epsilon RI-mediated cytotoxicity, indicating down-regulatory effects of Fc epsilon RII/CD23 on Fc epsilon RI-dependent functions. These results demonstrate functional properties for Fc epsilon RI on platelets and indicate unsuspected interactions between the low- and the high-affinity IgE receptors.

Abstract
The mechanism by which specific immunotherapy exerts its beneficial effect remains unclear. In order to evaluate the influence of venom immunotherapy on the T-cell cytokine pattern of allergic reactions, we studied interleukin-4 (IL-4) and interferon-gamma (IFN-gamma) mRNA expression of peripheral T lymphocytes from 12 patients undergoing rush venom desensitization, before treatment at Day 0 (D0), at Day 15 (D15) and Day 90 (D90) after treatment, and from seven controls. Antigen-specific T-cell proliferation was also determined. Cytokine mRNA expression was evaluated using in situ hybridization, 24 hr after culture of peripheral T cells with medium, venom, or an unrelated allergen. Allergen-induced T-cell proliferation decreased at D15 and D90 of rush immunotherapy (P < or = 0.02). In venom-stimulated cultures of the patient group, there was a decrease in IL-4 mRNA-positive cells at D15 and D90 (P < or = 0.001). Before desensitization, IFN-gamma mRNA expression was lower in patients than in controls and did not increase after in vitro allergen stimulation. In contrast, after immunotherapy, spontaneous IFN-gamma mRNA expression increased, but only at D90 (P < or = 0.001). The cytokine pattern observed at D90 after immunotherapy was similar to that observed in control subjects. In conclusion, venom immunotherapy induced an altered cytokine mRNA pattern in allergen-stimulated T cells which was dissociated from the early changes of allergen-induced T-cell responsiveness.

Abstract
Since the first report in 1983, blood platelet reactivity from patients with immediate hypersensitivity reactions, and particularly allergic asthma and aspirin-sensitive asthma, has been evaluated by the release of cytotoxic mediators able to induce the death of parasite larvae, and by the generation of oxygen derived free radicals, measurable by chemiluminescence. We demonstrate here that platelets are able to reduce MTT tetrazolium salt proportionally to the stimulation level in two models of platelet triggering, one IgE-dependent and one aspirin-dependent. This method correlated significantly with the cytotoxicity assay of platelet stimulation (r = 0.965, p < 10(-5) for IgE-dependent stimulation; r = 0.723, p < 10(-4) for aspirin-dependent stimulation). The MTT colorimetric assay should complement or possibly replace previous methods of assessing platelet activation which were of limited use allowing broader investigations on the involvement of platelets in immune processes and in allergic or pseudoallergic reactions.

Abstract
Using decreasing concentrations of PAF-acether or thrombin, it was possible to observe on human platelets, first, aggregation, classically associated to activation, then , below a threshold, cytotoxicity towards Schistosoma mansoni larvae, proposed here as stimulation. These two activities appeared as distinct and antithetic. However, their induction might be the consequence of triggering of the same receptors with different intensity, since PAF-induced, but not thrombin-induced, cytotoxicity could be inhibited with specific PAF-antagonists BN 52021 and BN 52024 also known to inhibit PAF-induced aggregation. These results give credit to the hypothesis that haemostatic and cytotoxic properties of platelets are two distinct functions of these blood elements.

Abstract
Recently, it has been shown that platelets, through a receptor for the Fc fragment of IgE, could be specially triggered by venom allergens in hypersensitivity to hymenoptera, generating cytocidal mediators toward Schistosoma mansoni larvae, and oxygen metabolites measured by chemiluminescence. After rush immunotherapy, a depressed platelet response was demonstrated to be associated with the production of lymphokine(s). Here we report the characterization of a factor present in supernatants of antigen-stimulated T cells from patients after hymenoptera venom desensitization which is able to inhibit platelet cytotoxic functions in a dose-dependent manner. The optimal inhibition was observed with supernatants obtained after T lymphocyte stimulated with 10(-5) micrograms venom allergen/ml. Once specifically produced the platelet-suppressive effect of lymphocyte supernatants was not antigen specific. The producing T cell subpopulation was identified as CD8+. This lymphokine had an approximate molecular mass of 25 kDa and a pI of 4.8. It was heat and acid stable and sensitive to trypsin and proteinase K but not to neuraminidase. This platelet inhibitory activity was absorbed by platelet membrane suggesting its binding to a receptor. These properties were very similar to a previously described platelet activity suppressive lymphokine, suggesting the participation of this lymphokine in the mechanisms of rush desensitization.

Abstract
1. Blood platelets from patients with aspirin-sensitive asthma (ASA) generated cytotoxic mediators in the presence of aspirin. This abnormal in vitro response to aspirin was abolished within 1 h after nedocromil sodium inhalation but not after sodium cromoglycate inhalation. 2. Platelets recovered this reactivity to aspirin by 12 hours after nedocromil sodium treatment of ASA-patients. 3. The in vitro reactivity to aspirin of ASA platelets isolated before inhalation was inhibited in the presence of serum isolated 15 and 60 min after nedocromil sodium inhalation.

Abstract
We demonstrate here that a second mechanism of platelet activation dependent on lymphokine could also take place in the expression of platelet cytotoxicity against Schistosoma mansoni in vitro. Indeed, IgE, as previously described, but also IFN-gamma, present in the sera of infected rats, together induce platelets from normal rats into cytotoxic effectors for the parasitic larvae. This second mechanism appears also effective in vivo since the passive transfer of normal platelets treated by recombinant IFN-gamma (rIFN-gamma) and the administration of rIFN-gamma to rats conferred a protective immunity to S. mansoni.

Abstract
In a previous study we demonstrated that mitogen-stimulated CD8+ CD4-T cells from normal donors produce a suppressive lymphokine (PASL) of IgE-dependent platelet cytotoxicity. Here we demonstrate the production, after antigenic-stimulation, of this suppressive factor during ongoing infections by Schistosoma mansoni in man and in the rat. The T lymphocyte subpopulation producing this factor was also identified as expressing the marker of the suppressive subset. Because of the absence of species restriction, the relevance in vivo of PASL was determined in the rat model. In these conditions we observed a complete abolition of the protection normally conferred against a challenge infection by the passive transfer of platelets from immune to normal rats after treatment of transferred platelets with T lymphocyte supernatants.

Abstract
Cetirizine is a new anti-allergic compound with a potent, long-acting, and specific antihistaminic property. Strongly active in the therapy of urticaria and seasonal or perennial rhinitis, it has been shown to inhibit the in vivo eosinophil attraction at skin sites challenged with allergen in atopic patients. In the present work, we confirmed that, at a therapeutical concentration, this molecule had a potent inhibitory action in vitro on eosinophil chemotaxis induced either by N-formyl-Met-Leu-Phe or platelet-activating factor and also on the IgE-dependent stimulation of platelets. These observations appear in favour of a possible role for cetirizine in the modulation of inflammatory cell interactions in allergic processes.

Abstract
Human recombinant interferon-gamma (IFN-gamma) significantly increased the expression of receptors for IgE (Fc epsilon RII) on blood platelets. Fc epsilon RII was measured by specific binding of 125I-labeled IgE or flow cytometry experiments. Scatchard analysis of 125I-labeled IgE binding curves revealed that treatment with IFN-gamma increased the number of Fc epsilon RII but did not change the value of the association constant of Fc epsilon RII for 125I-labeled IgE. IFN-alpha had no effect on the expression or affinity of Fc epsilon RII. In addition to Fc epsilon RII, IFN-gamma also modified the expression of the glycoprotein IIb-IIIa complex on the platelet membrane.

Abstract
The activity of the synthetic immunomodulator LF 1695 on the efficiency of two effector cell populations--macrophages and blood platelets--involved in IgE-dependent cytotoxic processes against parasites, was evaluated. Oxygen metabolite production and anti-parasite cytotoxic properties of both macrophages and platelets were increased following LF 1695 treatment in vivo (in rat) or in vitro (in rat and in man). The phagocytic properties of rat peritoneal macrophages were also potentiated by their in vitro incubation with the drug. In addition to these effector functions, the lysosomal enzyme content and the migration ability of rat peritoneal macrophages were stimulated after incubation with LF 1695. In the presence of the drug, rat macrophages were also shown to produce increased level of IL-1--measured by the mitogen-induced proliferation of murine thymocytes--when compared to unstimulated phagocytes. Finally, the oral treatment of rats with LF 1695, in the course of an experimental infection with schistosome parasites, induced a higher degree of immune protection (80%) against a challenge infection than untreated, infected control rats (40%). These results bring evidence of a stimulatory role for LF 1695 on immune effector functions of cells participating to defense mechanisms against multicellular pathogens.

Abstract
The IgE-dependent stimulation of mononuclear phagocytes and blood platelets can be measured by antiparasite cytotoxicity, oxygen-mediated chemiluminescence and, in macrophages, lysosomal enzyme activity. Using these parameters, the present study demonstrated an inhibition by nedocromil sodium of the IgE-mediated triggering of the nonmast cell inflammatory populations in the rat. These observations suggest that nedocromil sodium may be of value in the modulation of IgE-dependent cell activation inducing the release of inflammatory mediators.

Abstract
A possible relationship between binding sites for Immunoglobulin E (IgE) on human platelets, involved in IgE-dependent cytotoxic functions of platelets against helminth parasites, and well-characterized platelet constituents involved in haemostasis, was investigated. We first explored the interaction with IgE of platelets from patients with rare inherited deficiencies of defined platelet constituents and functions: Glanzmann's thrombasthenia, Bernard-Soulier and grey platelet syndromes. We report that only type I and II thrombasthenic platelets, which lack the membrane glycoproteins (GP) IIb and IIIa, failed to bind IgE and to exhibit IgE-dependent effector functions. Since thrombasthenic monocytes, however, showed normal interaction with IgE, this defect appeared restricted to platelets. Polyclonal and monoclonal antibodies directed against GP IIb-IIIa complex, but not monoclonal antibody directed against GP Ib, inhibited the binding of IgE to normal platelets, and their IgE-dependent cytotoxicity. Taken together, these findings indicate a relation between the GP IIb-IIIa complex and the expression of IgE binding sites and IgE-dependent effector functions in human platelets.

Abstract
Highly purified blood platelets from man and rat could be induced into cytotoxic effectors against schistosome larvae by an IgE-dependent mechanism. Such a process implied the existence of a receptor for the Fc part of IgE on the surface of these blood elements. Normal platelets, incubated in the serum of infected individuals as well as in the IgE-rich serum from asthmatic patients, showed similar capabilities. Flow cytofluorometric analysis evidenced that the platelets bearing IgE receptors represented a subpopulation (20%), the percentage of which was significantly increased (up to 50%) in rats or patients with high levels of circulating IgE. Radiolabeled IgE, whose binding was specifically inhibited by an excess of unlabeled IgE or by anti-Fc epsilon receptor antibody, allowed the demonstration that the receptor for this isotype on the platelet surface was saturable. The binding of increasing amounts of IgE followed a bimodal curve, with less than 1000 sites per platelet showing an affinity coefficient of 3.3 X 10(7) M-1 at low concentrations, and a Ka of 7.8 X 10(5) M-1 for higher concentrations. Beyond their interest in the demonstration of cytotoxic properties of thrombocytes, these observations place emphasis on the potential role of the platelets in immediate-type allergic reactions by their direct interaction with IgE antibody molecules, through a specific receptor.

Abstract
In rats infected with the parasite Schistosoma mansoni, the concentration of C-reactive protein in the serum increases after the lung stage of infection and is at its highest at the time of terminal worm rejection. The peak of platelet-mediated cytotoxicity induced by infected serum that has been heated (and is free of immunoglobulin E) as well as the time course for the development of platelet cytotoxic activity in infected rats was found to be correlated with the concentration of C-reactive protein. Rat and human platelets treated with homologous serum obtained during an acute phase of inflammation or with purified C-reactive protein were able to kill the immature forms of the worm in vitro. Platelets treated with C-reactive protein were furthermore capable of conferring significant protection against schistosomiasis in transfer experiments. Collectively these data indicate that a system that includes C-reactive protein and platelets participates in the natural resistance of the rat to schistosomal infection.

Abstract
The pathogenesis of aspirin-sensitive asthma remains unknown. Using a new model of platelet activation, initially described as a response of platelets to IgE antibody-dependent stimuli, this study was designed to test the hypothesis of a possible involvement of platelets in aspirin-sensitive asthma. Washed platelets from 35 aspirin-sensitive asthmatics showed an abnormal in vitro response to cyclooxygenase inhibiting nonsteroidal anti-inflammatory drugs (NSAIDs)--aspirin, indomethacin or flurbiprofen--characterized by the generation of a cytocidal supernatant and (14 patients explored) a burst of chemiluminescence; these drugs had no similar effect on platelets from 31 controls (p less than 0.0001). It was shown that the abnormal platelet response to NSAIDs was not mediated by IgE. In contrast to platelets, aspirin-sensitive asthmatic leukocytes generated neither cytocidal factors nor chemiluminescence in the presence of NSAIDs. Sodium salicylate and salicylamide, which, though structurally similar to aspirin, do not inhibit cyclooxygenase and are well tolerated by aspirin-sensitive asthmatics, did not activate their platelets to release cytocidal factors. Moreover, preincubation of platelets with sodium salicylate, salicylamide or prostaglandin endoperoxide PGH2, highly prevented their abnormal response to NSAIDs (greater than 80%; p less than 0.0001). Since several lipoxygenase inhibitors (NDGA, esculetin), including inhibitors of both cyclooxygenase and lipoxygenase (ETYA, BW755c), did not activate patient platelets and prevented the subsequent abnormal response to NSAIDs, it is suggested that the abnormal platelet activation by NSAIDs is not only the consequence of an inhibition of cyclooxygenase, but also involves generation of lipoxygenase metabolites of arachidonate. Besides, platelets from 4 aspirin-sensitive asthmatics undergoing aspirin desensitization were found to have completely lost their abnormal responsiveness to NSAIDs. These findings represent the first identification in aspirin-intolerant asthmatics of a specific abnormal cellular response to drugs inducing asthmatic attacks and open new perspectives into the pathogenesis, prevention and diagnosis of this disease. They also provide support to the concept of a role for platelets in asthma.

Abstract
Several killing mechanisms against schistosomes have been described in vitro, involving cellular and humoral factors. Neutrophils, eosinophils--with an accessory role for mast cells--monocytes and macrophages have been shown to exhibit cytotoxic properties against Schistosoma mansoni larvae, in association with antibodies of various isotypes or with complement (reviewed in ref. 1). Lymphocyte participation in effector functions is mediated mainly through lymphokines inducing cytotoxic macrophages, and, in certain cases, directly by T cells. The experiments reported here show that platelets, taken from rats after specific periods of infection with S. mansoni, were able to kill schistosomula, and that normal human or rat platelets acquired toxic properties towards the same target in the presence of serum from infected individuals. The humoral factor involved in this process was shown to be IgE, and evidence was obtained of a Fc receptor for IgE on human and rat platelets. The passive transfer of immune platelets to normal rats conferred a high degree of protection towards a challenge infection by the parasite.
